An old Russian joke

An old Jew is sitting on a bench in Gorky Park studying a "Teach Yourself Hebrew" book. A KGB officer sits by him and demands to know what he is doing.

"I am learning the language of Heaven", he replies.

"Huh", says the KGB officer, "you should be learning the language of the OTHER place!"

The old man replies, "Actually, my son, I can already speak Russian."
